amdgpu_vm_pt_create(9)

📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_vm_pt_create — from the Kernel API Manual, bestie ✨

Okay so real talk: this little icon is a kernel function that makes a buffer object for a PD/PT. That's the whole vibe. It's giving "allocator core energy" and we're gonna walk through it together, no cap 🫶

🌸 NAME 🌸

amdgpu_vm_pt_create — create bo for PD/PT 💖

✨ SYNOPSIS ✨

int amdgpu_vm_pt_create (struct amdgpu_device *adev , struct amdgpu_vm
*vm , int level , bool immediate , struct amdgpu_bo_vm **vmbo , int32_t
xcp_id );

It returns an int, periodt. 🎀

🦋 ARGUMENTS 🦋

Every single param, laid out like a group chat role call:

  • adev — the amdgpu_device pointer. Literally the device itself, the main character 👑
  • vm — the requesting vm. She's the one doing the asking 🙋‍♀️
  • level — the page table level. Which floor of the page table tower we're on 🏢
  • immediate — use a immediate update. Yes, that's how the original words it, and yes I'm keeping it exactly as written 😭
  • vmbo — pointer to the buffer object pointer. Double pointer moment, obsessed 💅
  • xcp_id — GPU partition id. Know which partition you're in, iykyk 🔥

🎀 SEE ALSO 🎀

The Kernel file, and then a whole friend group of related functions — every single one, because I would never do you dirty by trimming the list:

Like, the whole page-table family tree is here and they all ate 🌈⭐

That's the page! Short and sweet, just like this manpage 🍓 Go forth and allocate responsibly, queen 💜🧚‍♀️
